Vigorito's Missed Brilliancy Prize
IM Dave Vigorito won his last round game, a crazy affair against fellow IM Andranik Matikozian, complete with sacrifices, time pressure, shifts in the initiative and spurned draws. But in this position, Vigorito had the chance to win the brilliancy prize (or would have, if one had been offered):



Here, with Black to move, Vigorito saw almost everything, including some brilliant points - but one idea eluded him.

Can you find what he missed? You have four advantages: you know something's there, you can move pieces around (though for best results, try to solve it, as they say, in your head), you don't have the pressure of a tournament situation to deal with, and your time is (relatively) unlimited. Even so, it's pretty tough!

The solution will be given in a few days. Please: do not use a computer or send in a comment with the correct answer!! (The first request is for your own sake - both instructionally and, more importantly, aesthetically. The second is for the benefit of those still working on it, but inclined to peek when an answer is given.)

I don't know what the "hard" solution is (I assume leading to mate), but there seems to be a fairly straightforward win.

There seems to be a fairly straightforward "King Hunt" leading to victory, but I'd guess I'm probably missing the "brilliancy"...

Yes, check-check-check etc. looks obvious, but one must work out the "etc." before concluding it's really that easy! (If it were that simple, Vigorito would have found it and my intro would have been less enthusiastic - if the position even made it to the blog at all.)

One thing that makes it a little easier is knowing there is a forced line of play. I looked at it for under 5 minutes without a computer (still haven't plugged in) and I think it works. I suspect there something way better than what I'm thinking about. I'll email privately to be disabused or confirmed.

The previous commentator (Alex H, I presume) sent in a line that I also found. It does win, but it's pedestrian compared to the best line. Keep looking!

There's a funny aspect to this position: Of all the 30 or so legal first moves for Black only Rc6, Be7, three Q moves on the diagonal, and arguably Kg8 fail to win for Black! However I see the value of the position if it's presented as mate in 8!

I ammend my last post to include some white squared bishop moves as undesirable (especially Bh3, but not Bxc2) nevertheless it's amazing how almost every move by Black wins.
The mating combo is nice.

Never mind again! I woke up with irrational exuberance this morning. Definitely exaggerated on the legal move thing and it's mate in 9. But if you clean it up you can make a good forced mate problem, maybe starting further up the line where Mr. Vigorito missed idea kicks in.
